How can we disable name entering screen in link
Like:-

If you mean the prejoin page, see:

Example: https://meet.jit.si/test17265473#config.prejoinPageEnabled=false

And how can we set the username?
I tried https://meet.jit.si/test17265473#config.prejoinPageEnabled=false&#userInfo.displayName=Shubh

https://meet.jit.si/test17265473#config.prejoinPageEnabled=false&userInfo.displayName=“Shubh”
